We saw several large volume keywords in different accounts with maxbids of around $1 being billed at around $300 per click.

To their credit, MSN noticed this pretty quickly — their email to us came in at the same time our internal systems were alerting to the cost anomalies…

Hopefully the untangling of the invoices and refunds won’t create too much a hassle to our engineers and accounting folks, but I suspect it will.

Yep – it hit me too, and the SSL Security Certificate on adCenter is invalid at the moment… MSN paused one campaign after it reached over $5,000 in one day.

Thanks for letting us know about this…
